Corneal congenital dysplasia includes conical cornea, large cornea, small cornea, flat cornea, etc. Patients can be treated with prescription lenses for correction and surgical treatment to improve their vision, but the specific treatment is related to the patient’s condition. Patients with conical cornea may have irregular astigmatism due to corneal bulging, and early patients can improve their vision by correcting astigmatism through keratoplasty. Patients with conical cornea who experience rupture of the posterior elastic lamina of the cornea and have poor results from wearing eyeglasses can be treated with intraoperative procedures, such as corneal transplantation, to improve their vision. As for the large cornea, small cornea, flat cornea, etc., most of them are accompanied by other congenital abnormalities of the eye. If the patient is accompanied by glaucoma and suffers from vision loss, the vision can be improved through surgical treatments, such as compound trabeculectomy. However, if the patient has no obvious symptoms of ocular discomfort, he or she can be followed up clinically for observation. It is recommended that patients with corneal anomalies should seek timely medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
